692 CALLISTIUM; LASAIA. By Dr. A. Seitz. 



however, the type of Nelone to which they are transferred in Stichels catalogue, a new name for the genus 

 would be necessary, if Nelone would give way to the (dispensable) Exo-plisia. 

 cadmcis. N. cadmeis Heiv. (132 h). Above sooty brownish-grey, more darkly clouded, beneath of a steel-blue 



reflection, on both surfaces with black transverse stripes, with a row of dots in front of the border and, on 

 the forewings, speckled, on the hindwings, white fringes. A series of comma-like streaks in front of the distal 

 margin are distinct particularly on the hindwing. Panama to Peru and South Brazil. Rare. 

 htcoides. N. incoides Schs. (= myrtis Drc.) (132 h). Scarcely half as large as cadmeis: above similar, but the 



fringes of the hindwing likewise speckled, the streaks in front of the border shorter and noticeable only in 

 a certain exposure to light. Beneath like above, not steel-blue. North Argentina, the adjoining Bolivia and 

 Peru; the figured specimen from Tucuman (North Argentina). 

 hijpocMoris. N. hypochloris Bat. has the size of cadmeis, white fringes being scarcely speckled on the forewings; 



also the upper surface of it is dark steel-blue, with black markings; beneath like cadmeis, without the small 

 black transverse streaks of the latter, but the whole surface of the wings darkened except the distal marginal 

 part being of an intense blue lustre. 



70. Genus: Callistiiiiu Stich. 



In the structure of the body it approximates Amarynthis, but the shape of the wings is quite diffe- 

 rent. Undoubtedly allied to Lasaia from which it forms the transition to Charis as which the only species 

 was originally described. Head uncommonly stout with protruding, furry eyes. The veins do not exhibit any 

 deviations. In its exterior similar to the preceding genus. Only 1 species. 

 cleadas. C. cleadas Hew. (135 i) resembles N. cadmeis so much that Staudixgbr took it to be the $ of it; 



but the (^ is beneath not blue, but shows the same colouring and marking as above. The transverse streaks 

 are thicker than in N. cadmeis and differently arranged. On the figure (according to a specimen from Onoribo) 

 we see very distinct white costal spots which, however, are absent in specimens from other districts. Guiana, 

 Amazon. Rare. 



71. Genus: liHsaia Bat. 



Of the shape of N. cadmeis, but the lustrous blue colouring is exhibited here on the upper surface, 

 while the under surface is marbled brown and grey; above greyish-brown. Head and thorax are robust, 

 the abdomen short and small, the antennae long, scarcely thickened at the ends, the wings slightly dentate, 

 particularly the hindwings. Costa of the forewing somewhat curved. The butterflies fly in day-time on flow- 

 ers, where they sit with their wings spread out horizontally, and they come to wet places on the road; the 

 blue colour glistens brightly in the sun, just like the Tharops in the company of which the Lasaia are often 

 found. Like the Charis, they belong to the more common species. As they sit very tightly on the flowers, 

 they are easy to capture as soon as they are drinking. 

 ■)»eri^. L. meris Cr. (135 g). Recognizable by a white spot at the middle of the costa on the upper surface 



of the (J hindwing, in which there is mostly (not always) a' small black dot. The typical, smaller, darker form 

 being brightly coloured beneath inhabits the district from Mexico to the Amazon; the larger form being beneath 

 arsis, more unicolorous, arsis Stgr. (135 g), goes from there to the south as far as Paraguay, Bolivia and Peru. 



The $2 are above smoky-grey with a slight greenish tinge. — Not very common. 

 stda. L. sula Stgr. Almost exactly like the preceding, though more sparsely marked in black; the costal 



area of the hindwings above dull honey-yellow. Mexico to Colombia. The 9 i? not before me. 



arjesilas. L. agcsilas Latr. (135 g, h). Above not so very black as the preceding, the small black transverse 



streaks more united to chains, the costa of the hindwing without a white spot, blackish. The $2 are uni- 

 colorously dark grey, on both surfaces very similar to Call, cleadas (153 i). South Brazil and Paraguay. — 

 narse.s. narses Stgr. (135 h), from the Amazon to the north as far as Central America, has a more blue than green ground- 

 colom- of the ^(^ and a black half -band behind the cell. — Common; nor are the $$ drinking from blossoms 

 like the (J(J rare. The butterfly figured by us t. 135 i as ,,sessilis", differing from narses only by a greater 

 regularity of the half-band behind the cell of the forewing and a clearer, less black striated discal part of 

 the upper surface of the ^, is not that species, but merely the Mexican form of narses which needs scarcely 

 be denominated specially. Whereas 



sessUis. L. sessilis Sells. (14:2f) which can probably scarcely be separated from sula, is smaller, above more 



obtuse and more violettish-blue, the small black transverse streaks being very regularly arranged. It has a 

 characteristic under surface being dirty fawn-coloured in the ^, both the wings are traversed by a faintly 

 iridescent, mother-of-pearl white band. Mexico, near JMisantla and Guerrero common. 



moeros. L. moeros Stgr. (= rosamonda Weeks) (135 h, as pura). The species is larger and of a brighter bluish- 



green reflection than the preceding, the black streaks finer, regularly united to rows, the under surface purer 

 kennethi. and more one-coloured, the distal part without any black speckles. Peru. • — kennethi Weeks (135 i) from
